No Fruit Fly Evolution Even after 600 Generations

In 1980, this search for proof led researchers to painstakingly and purposefully mutate each core gene involved in fruit fly development. The now classic work, for which the authors won the Nobel Prize in 1995, was published in Nature.2 The experiments proved that the mutation of any of these core developmental genes―mutations that would be essential for the fruit fly to evolve into any other creature―merely resulted in dead or deformed fruit flies. This therefore showed that fruit flies could not evolve. LINK

Our schools only teach the theory of evolution even though we can't replicate the theory with experimentation on simple creatures. Funny that. :shrug:
